Whitson is going to sit out the entire season, after undergoing an arthroscopic procedure on his throwing shoulder Thursday.

Newschannel 7 Sports spoke with Karsten's father Kent Thursday afternoon, he confirmed to us that procedure done by Dr. James Andrews in Gulf Breeze.

Whitson had been throwing between 92 and 97 for short bursts leading up to the start of the season, but he was still feeling discomfort in that right arm.

His father says the coaches at Florida were working to get to him adjust his motion to avoid or deal with that discomfort. The Whitson's chose instead to try to figure out the cause of the pain.

Dr. Andrews found what he termed an impingement in the shoulder, and removed it.

The scoping though will require 6-8 weeks of rehab, and by the time Karsten goes through the protocol to pitch again, the season will be over.

Kent says his son is very disappointed to have to sit out the season, but adds Karsten's happy to finally know the cause of his arm pain, and looks forward to pitching again without discomfort. He says Karsten will take a redshirt, and still looks forward to pitching again at Florida, though they will take a look at what happens in the draft.

Remember coming out of Chipley in 2010, Karsten was the 9th overall pick but turned down a 2 million dollar signing bonus from the Padres.

Whitson missed the first month of the 2012 season with that same discomfort in that throwing arm. That following a stellar freshman season which culminated in a trip to the College World Series for him and his team.
